Description

TECHNICAL FIELD
This invention relates to posts, battens and the like which have a number of uses, one example being the construction of permanent or semi-permanent fencing.
BACKGROUND ART
New Zealand Patent No.s 212487, 214830 and 217784 describe elements of a fencing system based on a metal post. The fencing system has been sold in New Zealand and elsewhere under the name STAPLELOK™, and has substantial advantages when compared with conventional (timber and metal) post and batten fences.
The STAPLELOK system provides ease of handling, it is fast to erect, versatile and flexible.
In recent times a market has developed for more robust fencing systems for horticultural building and security applications, one of the requirements of this market being that the relative movement of horizontal fence wires in an installation should be minimised, and increased torsional strength is also desirable.
One object of the present invention to provide improvements to metal fencing systems which will increase the versatility and strength of the systems and which will address the above-mentioned needs.
Further objects and advantages of the present invention will become apparent from the ensuing description which is given by way of example.
Disclosure of the Invention
According to the present invention there is provided an elongate post of substantially rectilinear body having, on a substantially flat face, an open channel having two parallel channel sides defined by adjacent inwardly turned edges to which attachments can be made, characterised in that the channel sides having opposed serrated faces, each channel side terminating at an inner end, said opposed serrated faces co-operating to provide a series of aligned apertures with respect to which attachments can be secured.
The serrated edges can be regular and of a generally saw-tooth configuration with the tips of each coincident.
The inner faces of the inwardly turned edges at the widest point can be provided with a surface which is substantially parallel with the said face.
Posts as aforesaid can be used to support a series of spaced fence wires, the fence wires being secured to the posts by staples driven into the openings of the posts.
The staples can be two-pronged staples each prong being joined by a common limb and each staple engaging with a separate part of the opening of said face.
The locating face of said inner edges can be co-planar with the ridge of the spike of each staple prong.
The post can be secured to a structure to support a wall lining or such like of a building.
There is also provided a method of manufacturing a post as aforesaid comprising the steps of feeding an elongate plate to a roll-forming apparatus, serrating side edges of the elongate plate and shaping the plate into a box-section.
The side edges can be shaped prior to being serrated.
The serration can be achieved by a pair or pairs of complimentary toothed wheels.
Moreover, there is provided a fence comprising a plurality of elongate posts as defined in claim 1.

Figure 6:
is an enlarged cross-section at the opening of the post of Figure 2 showing a fastener fixed thereto, and
Figure 7 to 11:
illustrate a method by which the post of Figure 2 can be formed from a flat metal plate.
BEST MODE FOR CARRYING OUT THE INVENTION
With respect to the drawings and by way of example a simple horizontal wire fence comprises posts generally indicated by arrow 1, intermediate battens generally indicated by arrow 2, and a plurality of horizontal fence wires 3. The posts 1 are driven into the ground and the battens 2 span the fence wires from top to bottom. The fence is erected by driving the required number of posts 1 into the ground securing wires 3 to the posts using staples or other means, tensioning the wires and then fixing the battens 2 at desired intervals.
With respect to Figures 2 to 6 of the drawings a post 1 in accordance with the present invention has a substantially rectilinear body 4 having a front face 5 with an opening generally indicated by arrow 6 therein.
Opposite faces of the body 4 may be of complementary equal or unequal lengths. Each post may be provided with a cap (not shown) which protects the tip of the post against impact.
Preferably the body 4 is constructed in metals as aforesaid although other materials may be suitable.
The opening 6 is defined by two inwardly turned free edges 7 which are serrated such that tips of the free edges meet or nearly meet at 8 at intervals with sockets 9 being provided between. The front face 5 thus presents a series of sockets 9 to which fasteners or other attachment means can be secured.
The New Zealand STAPLELOK™ patents previously referred to describe how a staple can be driven into a channel between flanges of posts to secure wires or other attachments to the posts.
The opening 6 of the post of the present invention also facilitates the attachment of staples and other accessories in a somewhat similar manner with the important exception that the opening 6 is an open channel and the arrangement of the present invention prevents longitudinal movement of the staple (movement in a vertical plane when a fence is erected). It is noted that the inner-most parts 10 of the edges 7 are substantially parallel to the front face of the post, and that the sockets 9 are wider than they are deep.
The staple illustrated (Figures 5 and 6) has arms generally indicated by arrow 11 which are generally spear-shaped having a tip part 12, divergent sides 13 which lead to a shoulder 14 where the arm narrows to be a predetermined width W larger than the width WO of the sockets 9 in the front face 5 of the post 1.
The post 1 can be formed by roll-forming from a flat sheet of material with rollers gradually making each bend in the body of the post and forming the serrated free edges 7. At the end of the roll-forming process the closed edges 7 are near contact at intervals discussed.
The resilience of metal allows arms 11 of a staple or other fixture to be driven into the sockets 9 by momentary and localised parting of the free edges, sufficient to allow the widest part of the shoulder 14 to pass through the sockets 9 whereupon shoulders 14 locate with tips 8 of the edges 7 on the post which, in the absence of a forced re-opening of the opening, the matching of the shoulder and edge secures the arms 11 against withdrawal. As discussed, the closed faces 8 prevent the arms 11 sliding on the post. Any twisting of arms 11 also locks the arms further securing against withdrawal.
The post described is considered to have the significant advantages of being more robust than its predecessors and whilst maintaining all of the previous advantages, the serrated face allows staples and attachments to be securely fixed and the post configuration provides resistance to torsional and other bending forces which may be imposed on it.
Mentioned earlier was the fact that the posts described may be useful in other applications, for example as studs and noggings to support wall/ceiling boards or for providing protection and support for ducting, suspended ceilings, pipes, electrical wires.
With respect to Figures 7 to 11 of the drawings, the post of the present invention can be formed by roll-forming apparatus. The roll-forming apparatus is not shown in full in the line drawings but supports and rollers are shown in broken outline.
In Figures 7 to 11, a metal plate 16 is progressively formed into the post previously described.
In Figure 7 the metal plate 16 is presented to supporting roller 17.
Beyond roller 17, the edges 18 of the plate 16 are bent as the plate passes between complimentary rollers 19, 20.
Beyond rollers 19, 20, the plate 16 passes between complimentary rollers 21, 22 which have toothed ends 23 and the edges 18 are serrated.
Beyond rollers 21, 22 (Figure 10) the metal plate is formed into the box-shape indicated by rollers 24, 25, intermediate rollers (not shown) and at the finishing point roller 26 which has a thin central fin 27 centralises the metal section.
Aspects of the present invention have been described by way of example only and it should be appreciated that modifications and additions may be made thereto without departing from the scope thereof as defined in the appended claims.
